Rockstar last patch didn't fixed the game innability to set resolutions on launch: If in game res and Hz are not EXACTLY as desktop ones it start in windowed mode I.e if i set in game fullscreen 1080p 59Hz and desktop is set to 1080 60 Hz this give GTA V windowed mode on launch. It must be 59 Hz. :3eyes: I tried to see the limits of 1080 maxing ALL in game (ultra and higher value in each graphic option) with my crossfire (1150/1600) and i don't get good results. Spoiler The GPUs usage is at 85-98% (never 99% locked), CPU are around 70-80% and frames are in 100-110 range if i don't move. The problem is the values is when i move around these values are lowered to GPU 52-80% and CPU 60 in first and 45 in fourth core with frames lowered under 40 fps. I tried with lower resolutions (even 768p) and the results are similar: GPU is never fully used.
